(Cl. 139--255) This invention relates to improvements in bob bin receivers for weft replenishing looms and it is the general object ef the invention to provide a receiver including a bag which is supported and reinforced by a frame which holds it in normal position and by which it may be inverted to empty the bobbins in it. It is customary to provide a bobbin collector for bobbins which are discharged from the shut tle during the weft replenishing operations. In l0. an application filed on even date herewith I have set forth a bobbin receiver having a frame which supports a bobbin receiving bag the front part of which is connected to vertical members of the frame by lacing or the like. It is an important object of my present invention to construct the bag in such a way that it will be reinforced by the frame, more particularly the vertical mem bers thereof which extend alo-rig the front cor ners of the bag. . . 2 l Fig. 4 is a side elevation looking in the direc tionof arrow 4, Fig. _3,v , Fig. 5 is an enlarged horizontal section on line 5_5, Fig. 1. Fig. 6 is an enlarged front elevation looking in the direction of arrow 6, Fig. 1, and Fig. 7 is a view similar to Fig. 6 but showing the modified form of the invention. Referring particularly to Figs. 1 and 2, I have shown .a loom frame ID and a lay II supporting a shuttle box I2 which receives a shuttle S. `Dur ing replenishing operations of the loom the ex hausted or _depleted bobbins are discharged downwardly from the shuttle and are guided for wardly by a bobbin chute I3 secured to the‘lay under the box I2. The bo‘bbins are ordinarily dis charged when the lay is at so-called front center or in the left `hand position thereof as viewed in Fig. 1.. `During loom Voperation the chute I3 20 swings back and forth >along a path under the shuttle box. ‘ ' The frame has a removable pivotal connection The receiver -R for the discharged bobbins com with a support fixed `to the loomside and it is prises essentially three parts, a stand I 5, a metal another object of the invention to construct this frame F, and a cloth bag B. The stand or support support in such manner that the lower part of the bag can move backwardly and forwardly between v25 I 5 is secured to the loom` frame as at I6 and pro jects outwardly therefrom, or to the right as parts of the support when being placed in nor viewed in Fig. 2. The support is formed with a mal position or being removed for the purpose of bottom cross bar I‘I and right and left uprights emptying the bobbins. `I8 and I9, respectively, as viewed in Fig.. 3.

The upper Fig. 1 is a side elevation of a part of the loom, end of each of the side members is bent rear partly in section and showing the preferred form wardly and inclined Ydownwardly to form a sup yof my improved bobbin receiver in normal posi porting arm 33. ‘ . tion, Fig. 2 is a front elevation looking in the direc tion of arrow 2, Fig. 1, Fig. 3 is an enlarged detailed `front elevation of the support looking >in the direction of arrow 3, 1, 50 Each side member 3i] and 3l is provided near the lower end thereof with a iitting 35 formed with a lug or boss 36 for cooperation `with the associated spring 25. The fittings 35 `may be vsecured to .their »respective Vside members in any 65 `approved `manner ‘ as `by soldering before the ' 4 frame F is bent at its upper end to provide the arms 33. The lugs or bosses 35 project outwardly from the vertical center of the frame F and are preferably in horizontal alignment, as are also the springs 25. The bag B is made of cloth and has inner and outer side walls 31 and 38, respectively, a rear wall 39, and a front wall 40. These walls extend l upwardly and provide the bag with an open bob bin receiving mouth M. Each of the inner and outer side walls is provided with upwardly ex- . tending straps or loops 4| through which the arms 33 extend, as shown in Fig. 1. Each ver tical front corner of the bag is .provided with an contained therein. During this emptying opera tion the side members 30 and 3l support the forward part of the bag. Y When the receiver is returned to normal posi tion the cross bar 32 thereof is placed between the stops 23 and slippeddown into the recess 22, after which the receiver is pushedk rearwardly until the lugs 36 pass under the spring clips 25. The latter not only prevent upward movement of the receiver until after the latter has been moved forwardly of the path of the chute I3, but also assist gravity in holding the receiver ' in its normal position. During return movement of the bag to its normal position the lower part elongated hem 42 through which extends the as 15 thereof will pass through the space 55 and assume the position shown in Fig. l. The hems 42 are sociated side member 35 or 3l. These hems sufliciently wide to be slipped over the fittings extend downwardly a considerable distance along 45 and 5i! when the bag is 'attached to frame F. their side members and end in the vicinity of From the foregoing it will be seen that I have the upper ends of the uprights I8 and I9.

The right and left hubs 45 are provided with opposite hand threads and the opposite ing from the spiritV and scope of the invention and I do not wish to be limited to the details herein disclosed, but what I claim is: l.
